The  thickness  of  the  cast-iron  pipes  given  in  this  table  were  calculated  by 
the  following  formulas: 

For  diameters  greater  than  36  ins.,  t  =  .00003  II  D  +  .0125  D  +  .33;  for  di- 
ameters of  36  ins.  and  less,  t =.03003  H  D  +  .01  D  +  .30;  t  =  thickness  in  decimals 
of  an  inch;  D  =  diameter  in  inches;  H  =  head  in  feet.

The  thickness  of  the  Class  A  pipe  was  based  upon  a  static  pressure  of 
10(>  ft.,  and  the  Class  B  pipe  upon  a  static  pressure  of  180  ft. 

The  figures  include  the  cost  of  pipe,  gates  an  I  "  specials,"  the  cost  of  cart- 
ing, laying  and  setting,  and  excavating  and  back-filling  for  the  same,  and  all 
other  expenses  generally  incurred  in  ordinary  water  pipe  laying,  with  the 
exception  of  the  cost  of  hydrants. 

The  cost  of  "specials"  was  based  upon  $0.025  per  pound,  with  pipe  at 
$30  per  ton,  the  cost  of  air-cocks  (used  only  with  pipes  having  a  diameter 
larger  than  20  in.),  at  $10  each,  and  the  cost  of  the  gates  the  same  as  given  in 
Table  No.  3. 

Ordinary  labor  was  considered  at  $1.50  per  day. 

Depth  of  Pipe.— The  depth  of  the  axis  of  the  pipe  below  the  surf  ace  of 
the  ground  has  been  considered  in  all  cases  as  4.67  ft.

This  table,  No.  5,  contains  the  items  in  detail  from  which  the  cost  of  the  labor 
of  laying  water  pipe,  from  4  to  24  in.  in  diameter,  given  in  Table  No.  3,  were 
obtained. 

The  word  "Trenching"  is  used  for  excavating  and  back-filling. 

Throughout  these  tables  Easy  Digging  is  intended  to  correspond  to  exca- 
vation in  sand,  etc.;  Medium  Digging  to  excavation  in  sand  and  gravel,  etc.; 
and  Hard  Digging  to  excavation  in  hard  or  moist  clay,  etc.  The  figures  relat 
ing  to  medium  excavation  are  probably  the  most  reliable  for  pipes  that  have  a 
diameter  greater  than  8  ins. 

The  prices  given  in  any  of  the  tables  do  not  include  the  cost  of  engineering 
and  inspection. 

SUPPLEMENT  TO  TABLES  NOS.  2,  3,  AND  5. 

The  following  table  gives  the  items  of  the  actual  cost  of  the  labor  of  laying  water  pipe 
ana  excavating  and  back-filling  for  ihe  same,  upon  which  Tables  Nos.  2,  3  and  5  were 
based,  with,  the  exception  of  the  cost  of  carting  pipe,  which  was  considered  at  $1.00  per 
ton.  The  table  also  shows  a  comparison  of  the  items  of  actual  cost  with  the  amountx 
that  correspond  to  them  in  Tables  Nos.  2,  3  and  5.  The  tabl"  was  computed  from  rec- 
ords kept  in  Providence,  with  the  exception  of  the  data  that  refers  to  the  48-twc/i  pipe, 
which  was  obtained  elsewhere.

In  this  table,  under  the  division  headed  "At  $0.30  per  Cubic  Yard,"  the  cost 
per  lineal  foot  of  Trenching,  etc.,  is  based  upon  the  excavation  at  $0.30  per 
cubic  yard,  measured  in  the  trench,  instead  of  the  actual  cost,  and  takes  the 
place  of  the  amounts  charged  in  Table  No.  5,  for  medium  digging,  to  trench- 
ing, teaming,  and  %  the  amount  charged  to  foreman  and  tools,  etc.  (ex- 
clusive of  the  cost  of  blocks  and  wedges,  which  are  included  in  the  cost  of 
Tools,  etc.,  for  24-inch  pipe,  in  Table  No.  5).  The  figures  relating  to  laying,  etc., 
are  the  same  as  those  charged  in  Table  No.  5  for  medium  digging,  to  laying, 
calking,  lead,  carting,  and  %  the  amount  charged  to  foreman  and  tools,  etc. 
(exclusive  of  the  cost  of  blocks  and  wedges,  which  are  included  in  the  cost  of 
tools,  etc.,  for  24-inch  pipe,  in  Table  No.  5).  In  each  instance,  in  calculating 
the  cubic  contents  of  the  trench,  the  width  was  considered  as  2  feet  more  than 
the  diameter  of  the  pipe  and  %  of  a  foot  deeper  than  the  water  line  of  the 
same.

The  cost  of  a  square  yard  of  broken  stone  £  ins.  thicfc,  put  properly  in  place 
in  a  street,  would  be  about  $0.40. 

The  figures  in  this  table  were  based  upon  a  trench  3  ft.  wider  at  the  surface 
of  the  ground  than  the  diameter  of  the  pipe,  in  order  to  allow  for  caving,  etc. 

The  cobble  stone  paving  was  considered  at  $ 0.30  per  square  yard,  the 
granite  blocks  laid  upon  sand  foundation  at  $0.45  per  square  yard,  and  the 
granite  blocks  laid  upon  a  concrete  foundation,  etc.,  at  $3.46  per  square  yard. 
The  granite  blocks  were  estimated  to  lay  from  24  to  27  per  square  yard.

The  labor  of  excavating,  back-filling  and  laying,  etc.,  was  considered  in  all 
cases  for  lead  pipe  at  $0.16  per  foot.  The  price  used  for  lead  pipe  was  $0.06  per 
pound,  and  the  price  for  tin-lined  lead  pipe  $0.12  per  pound.

Engineering  News  contains  each  week  twenty- 
four  pages  of  valuable  reading  matter,  cover- 
ing the  entire  field  of  engineering  science  in  both 
this  and  foreign  countries.  Railways,  water- 
works, bridges,  manufacturing  and  technical,  con- 
tracting, mechanical  and  electrical  industries  are 
fully  reported,  and  detailed  working  drawings 
and  full  descriptions  are  given  of  all  the  more  im- 
portant and  note  worthy  structures  and  enterprises. 
Record  is  kept  of  the  proceedings  of  the  engi- 
neering and  technical  societies  and  clubs,  and  the 
latest  technical  books  and  magazines  are  fully  re- 
viewed and  discussed.  The  correspondence  col- 
umns contain  communications  from  engineers, 
contractors  and  others,  regarding  matters  of  cur- 
rent interest. 

The  advertising  columns  and  those  of  "Con- 
struction News"  constitute  the  most  complete  rec- 
ord of  the  current  contract  work  of  engineering 
in  the  United  States  that  is  obtainable.  Together 
they  make  a  very  complete  index  of  new  rail- 
roads, new  water-works,  sewer  building,  street 
paving,  highways,  river  and  harbor  improve- 
ment, bridge  construction,  public  buildings  erect-

canals,  everything,  in  fact,  having  any  relation  to 
public  work,  or  the  business  of  civil  engineering 
and  contracting,  while  from  the  abstracts  of  bids 
published  from  week  to  week,  the  prices  of  labor, 
materials  and  other  elements  of  cost  of  engineer-
